Flat Track Racers- first National win by a Japanese bike

 On September 6 1970 Chuck Palmgren gave Yamaha its first national win on the Mile at Nazareth, PA. Mounted in a Trackmaster frame, the 650cc engine was hopped up by Palmgren himself, with CR Axtell doing the headwork. It wasn't till 1972 that the engine was enlarged to a full 750cc.
